<h2>Summary</h2>
<p>This module allows for control of the environment that will
be provided to CGI scripts and SSI pages. Environment variables
may be passed from the shell which invoked the httpd process.
Alternatively, environment variables may be set or unset within
the configuration process.</p>
<p>For additional information, we provide a document on <a
